PESSARY.

Specification of Letters Patent.

Application filed June 25, 1913.

Patented Oct. 6, 1914. Serial No. 775,743.

To Zl whom "it may concern Be it known that I, lvlrr'c-HELL BURDINE ARENDELL, a citizen of the United States, residing at McAlester, in the county of Pittsburg and State of .Oklahoma, have invented certain new and useful Improvement in Pessaries, of which the following is a specification. f V

The present invention relates to improvements in pessaries, and is designed for the purpose of providing a sanitary surgical instrument especially as a support in cases of prolapsus or displacement of the uterus, ovarian congestion or dilation of the uterine canal. One of the greatest objections to the use of many of the devices now in vogue for this and analogous purposes is the unsanitary condition surrounding the instruments, and this objection is overcome by the use of my novel provision of means for drainage of the organ.

The primary object of the invention is the provision of a simple and inexpensive, but thoroughly eflicient instrument for the purpose, and one that may be cleansed thoroughly and readily. The invention consists essentially in an instrument of this character having special construction rendering it'elastic to perform its required function and in the combination of drainage means for the instrument.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention, constructed according to the best mode I have so far devised for the practical application of the principles of the invention.

In the accompanying drawings: Figure 1 is a top plan view of an instrument embodying my invention. Fig. 2 is an elevation of the device. Fig. 3 is another elevation taken at right angles to Fig. 2. Fig.

4 is an enlarged sectional view taken on line H; of Fig. 1.

In the preferred embodiment of my 1nvention, l employ the stem 1 which is of gutta-percha or hard rubber, and the stem is formed with prongs 2, 3,' which at their respective ends are formed with enlargements or protuberances 4 and 5.. The upper end of the stem is cylindrical in cross section, with the addition that it is fashioned with a dovetailed lug or boss 6 complemena tary with a similar slot 7 in the head 8. The head 8 is also of hard rubber and is fashioned with a central opening 9 extending therethrough and of greater diameter than the cross area of the stem. The slot 7 is undercut from the central opening 9 and the head incloses the end of the stem and its lug. The head and lug are secured together by a metal screw 10, and the outer end of the opening for the screw is closed by a gutta-pcrcha or hard rubber plug 11. i

The presence of the hard hubber plug elimlnates the possibility of oxidation of the metal screw.

The use of the instrument will be understood by those skilled in surgery, it being sullicient to state that the elastic prongs are held together when the instrument is inserted into the organ and allowed to distend after insertion. The opening 9 provides an efficient means for drainage, and the instrument in actual use has proven highly satisfactory in correcting displacements and in';'

affording a support in case of prolapsus.

Having thus fully described my invenm m a? patent may be obtained for five acute each, byeedressinp'; the flommissioner of Patents.
